the linnille hin' iniiy he clamped to the teniper serew or released therefrom.

',llie means for locking the swivel eoinprises ii ke)7 21 slitlahly moniiteil in ii vertieiil recess: 2i). in the liiih 16 of the liiinille hzir, Suid retiens :intl key being. for exiiniple. ilovetziileil to retain the keyr in place sind the lower eiiil of :siiirl key engaging' with serriitions or notches 24 in the top ot' the swivel T, said key lining toothed, iis at 26, to engage in i1 plurality of siiitl notches. For operation of said key, l prefer to nwe :i hiinille ineiiihe'r 27 on the handle hm', the hiinille ineiiihers il() :intl 27 heilignt opposite ends of the handle hiir :intl siiiil lmnille 3T having :gi spinille 2S extending iii a enrresponiling hoi-e in the other iii'm of the handle hiir :intl being provided :it its inner enti with :i head 29 having' n spiral thingie ftkengiiging with grooves 31 in the key 2l, there heiner :i plurality of these grooves ziiirl the said spiriil lli-inge engaging successively with the grooves in the rotative morenieiit t the liefitl 29.

The operation iii zisfollows: The height of the toolfi` it; adjusted hy the rotation of the teii'ipei zere-w, the lninrlle hiir being elainipefl to the temper screw hy screwing in the iiieinhei' il() :intl the looking key 21 being :it this tiiiie'releiiswl from the swivel hy proper manipulation of the lizintlle mehr her 2T. Siieliini'ljietmr-int having been el? fectetl, the swivel looked to the temper screw by turning the handle hiir 27, So as to canse the spiral flange to depress the.

locking key Qllyii'ito engagement with Serrh tions.' 24 in the swivel. Drilling iniiy then [he iliroeeeflei'l; with iinil. the swivel will he 'held from. oscillation. by siioh engagement of the locking inem er 2l with the swivel.

It willhe noted thiit the swivel T is freely rotiitiihle relatively to the reins 3, e.\'i,.i-.pt,

when the key 2l is engiigeil :intl the. eliinip ineens t3 is tightened. This relative move ment or rotation of the parts when tlisconneeted is of iiniioi-tziriee in manipulation and :itljiistinenti ot' the several. parts in bringing the drilling tool to position or removing it 4from operating position.

Wha-t| I claim is:

1. The, combination with a cable of n. swivel connected thereto, n supporting temper screw on which said swivel is rotatably mounted, reins engaging said temper screw,

Said swivel being rotatable relatively to the reins, means for tightening the reins on the temper screw, a handle bar rotatably mounted on the temper screw, means for securing said handle bart-o the temper screw, and a locking' device movably mounted on the handle har and adapted to engage said swivel to hold the .swivel from rotation relatively to the handle bar.

2. 'lhe combination of a swivel provided with means for attachment and support of a "able and having a notched portion, a temper screw on which said swivel is rotatabl)V mounted, a handle har attached to said temper screw, and a locking member slidahly mounted in said handle bar and adapted to he engaged 'in siaid notched portion ot the swivel.

.3. The combination of a Swivel provided with means for attaclnnent and support of a cable and having; a notched portion, a temper .screw on which said swivel is rotat,ahl \Y mounted, a handle har attached to said temper screw. a key .slidably mounted in said handle har and adapted to be engaged in said notched portion of the swivel, and a handle member rotatably mounted on said handle bar ar 1 provided with means engaging said key to raise and lower the same.

4. The combination of a Swivel provided 1.1.) with mea-ns -for attachment and support of a cable and having a notched portion, a temper Selen' on which said swivel is rotatably mounted, a. handle bar attached to said temper screw, a -key slidably mounted in said handle bar and adapted to be engaged in said notched portion of the swivel, and a handle member rotatably mounted on said handle har and provided with meansengag ing' Said key to raise and lower the same, 40 said means eon'iprising a Spiral flange carried bysaid handle member, said y being provided with groovee engaging te said spiral flange.

In testimony whereof,-I have hereunto Set 4-5 my hand at Los Angeles California, thisY '19th day of November, 1910.
